The proposal to which that message refers was made before
Haskell really existed: we didn't know the concrete syntax
of the language, so I used arbitrary keywords. Even if we
look at Phil Wadler's subsequent tidying up of it, I'm not
at all sure how it fits with the language as it stands
now. So while it might make a reasonable starting point, I
don't think it yet counts as a concrete proposal!
I must say though, that I don't like the reasoning that we
can put in fractional fixities because it's a small
change. The way to hell is through a series of small
steps. If using integers to express fixities is a bit of a
hack, switching to rational numbers is a hack on top of a
hack.
